My invention relates to Fourdrinier paper machines-` @ne of the objects of `the invention is to provide a simple, practical and advantageous seonstruetion oi paper making machine, par tieularly of the Fourdrinier type. Another object oi the invention is to provide a Fourdrinier machine in which the table may he bodily removed in a sidewise lo manner to permit placing of neer Wire ain'^ may also be adjusted vertically at the 'feed end to control the iov/ of paper ma terial.

Another object of the invention is i prol vide practical and advantageous mechanism permitting this table reinovahility and feed end adjustihility.

another object of the invention is 'to aru range for the proper cooperation the 'table and 'pulp holding and .feeding devices in the removing and. adjusting niovements or" the tahle.

@ther objects of the invention will appear and he pointed out hereinafter.

Figs. `10 and 11 are cross sections taken on lines 10-10 and 11-1l, respectively, in Fig. 8;

Fig. 12 is a sectional view and posts; and v showing tracks Fig. 13 is aV cross-section taken on line renie in Fig. ie.

Referring 'to the drawings, l shon7 a Four drinier machine having a main table por tion 1 supporting rolls 2 for the Wire 3. in addiiional or supplemental end portion 1a also embodied. in the machine shown, the same supporting vacuum 'noires' 5-5 and G-6, and having a jointed connection, as hy pivot 7, with the main portion 1, and also 90 having rolls 8-8 and. 9 9 for the wire.

The table comprising the sections or por-- tions 1 and 18 is adapted igor bodily removal in a sidevviee manner, to permit the advantageous application of a new Wire after a one has heen removed. To such end provision is made for moving the tahle ont and hach sidewvise on tracks 11, 12 and 13, the table being shown in normal 'position in Fig. 2, and inoved out on said tracks in Fig. 3. The table is provided With'cnitable power mechanism for moving it out and hack on. said tracks, as for example, an electric motor 15, (Figs. 1 and 5) power-connected by spur Whe-el 16, gear 17, Worm 18, and Wheel 19 75 with driving shaft 2G' carrying wheel 2l for track-i3, said shaft 20 being coupled to shaft 20 carrying Wheels 22 and 28 iol' tracks 11 and 12, respectively. The rear or hack side of 'the talole is provided with Wheels 25H25 (Figs. 2, fl and 6), for traveling on ihe tracks 11', 12 and 13, said Wheels 25 heing preferably constructed, as shown in Fig. o, with outside portions 25"-25, for purposes to he described later.

Tracks 11, 12 and 13' are made in 'two setions and oi such length as to provide for the tahle in hol-,h ont and in positions and are supported by posts or pedestals 26, 27, 28 and 29. Posts 27 have means such as 90 holte 30 for adjusting tracks veripally, and other means such as 'bolts 31 and 32 for" adjusting and holding saine in vertical position. Posts 28 have adjustable memhers 33, carryin rollers 33 for supporting tracks, 9" and bo ts 34--311 for vertically adjusting inemhers 33' and thereby the tracks; also bolts 32-32 for maintaining tracks in verniu cal position. Posts or pedestals 28 have top euri-aces 37 which ere inclined slightly upward to elevate rollers 25 and thereby. permit tracks to be removed. Post 29 has a wheel 29a for, serving as a stop to limit backward movement of table. Posts 27 and 28 are preferablyconnected together in pairs by cross beams 40.

Thus it will be seen that the entire table may be moved out to permit changing wire by operating motor 15, and then move back by reversing motor, front edge of table normally resting with wheels 21, 22 and 23 on tracks 13, 11 and 12, respectively, and rear of table resting with wheels A25 on track surfaces of pedestals 28.

Inasmuch as table is preferably shaken by shaking mechanism, table sections 1 and 1 are preferably mounted at upper ends of flexible members 41-41 whose lower lends are connected to and su ported by side channel members 42-42, elow which the various track wheels 21, 22, ctc. are mounted, whereby table member 1 may be shaken relatively to 'members 42--42. The shaking mechanism shown herein comprises a vibratory member 43 mounted on a rock shaft 44 operated by vibratory member 47 actuated by driving members 48 and 49. Inasmuch as said shakin mechanism is shown, described and claime in another application of mine, executed of even date herewith, Serial No. 648,962, filed July 2, 1923, shaking mechanism for Fourdrinier machines, it will not be further described nor claimed herein.

In accordance with present invention, the

and feeding devices may be a justed vertically and 1n such relation as to cooperate properly in their various adjustments. This adjustment may `be secured by means of suitable elevating devices and connections for accomplishing the desired purposes. As

feed end of the table and the (pulp holding an advantageous arrangement I have shown an electric motor 65 mounted on the top member 66 forming with posts 67 framework on which the pulp holding and feeding devices are mounted. Motor 65 is geared to power shaft 68 so as to drive same and shaft 68y is connected by sprocket chain 69 with supplemental power shaft 70. The power shafts 68 and 70 raise and lower the feed end of the table 1 and feed box 71 through suitable mechanismv preferably controlling same, so that they shall rise and fall together in roper relationship, and also so ythat the feed) box shall be tilted toward the table as it rises and restored to level osition as it falls. The mechanism shown or accomplishing this result comprises two sets of vertically adjustable yokes 7S-73, and 74-74, whereof the yokes 73-73 are raised and lowered by plunger 7 3, having a worm and wheel connection with shaft 86, and whereof yokes 74--74 are actuated by plunger 74a (Fig. 1l), having similar worm and wheel connection with shaft 70.

Yokes 73 are connected with hangers 76 which engage the ends of projecting members 77 von a cross beam 78 which extends underneath and enga es feed box frame pieces l seen feed box 71 and feed end of table will rise and fall together.

As a matter of further and specific irnprovement, provision is made for tilting feed box 71 so that it will incline down toward the table as it and the table rise. For this purpose I show guideways 83--83 and 84- 84 on end posts 67 and slide pins `or rollers 85 and 86, the former on side frames 87 on feed box 71, and the latter on frames 88 on hangers 88a extending down below feed box 71, being preferablyformed integral with frames 9. Guideways 83 are preferably inclined inwardl and upwardl and guideways 84 outwar ly and upwar ly, as shown in Fig. 7, whereby feedbox 71 will in effect be tilted substantially about the feed end of table as both rise and fall, thus insuring proper feed of pulp and proper cooperation o f devices in the upward and downward adjustment. Guideways 83 may be adjusted by screw bolts 83aL and guideways 84 by screw bolts 84.

The brest roll on table is preferably made adjustable lengthwise of the table to facilitate applying a new wire and for other purposes. In the arrangement shown, said roll is mounted on slides arranged to slide in `-guideways 92 and provided with a rack 93 meshing with a pinion 94 on shaft- 95 also carrying gear 96 meshing with pinion 97 turned by handle 98, whereby rotation of handle 98 will adjust brest wheel 90 lengthwise of the table.

Certain subject matter of this application is disclosed and claimed broadly in copending applications of mine Serial Nos. 595,258, filed October 18, 1922; 648,959, 648,961, 648,962, filed July 2, 1923, and 205,006, filed July 11, 1927, and hence is not so claimed in this application.

It will be understood that changes and modifications may be made without departing from the spirit of the invention.
